Manifold linkages exist between climate change and sustainable development. Although these are starting to receive attention in the climate exchange literature, the focus has typically been on examining sustainable development through a climate change lens, rather than vice versa. And there has been little systematic examination of how these linkages may be fostered in practice. This paper examines climate change through a sustainable development lens. To illustrate how this might change the approach to climate change issues, it reports on the findings of a panel of business, local government, and academic representatives in British Columbia, Canada, who were appointed to advise the provincial government on climate change policy. The panel found that sustainable development may offer a significantly more fruitful way to pursue climate policy goals than climate policy itself. The paper discusses subsequent climate change developments in the province and makes suggestions as how best to pursue such a sustainability approach in British Columbia and other jurisdictions.

Despite the important role that tropical forests play in human existence, their depletion, especially in the developing world, continue relentlessly. Agriculture has been cited as the major cause of this depletion. This paper discusses two main theoretical underpinnings for the role of agriculture in tropical deforestation. First, the forest biomass as input in agricultural production, and second, the competition between agriculture and forestry underlined by their relative marginal benefits. These are supported by empirical evidence from selected countries in Africa and South America. The paper suggests a need to find a win–win situation to control the spate of tropical deforestation. This may imply improved technologies in the agriculture sector in the developing world, which would lead both to increased production in the agriculture sector, and would also help control the use of tropical forest as an input in agriculture production.

Tropical forest people often suffer from the same processes that threaten biodiversity. An improved knowledge of what is important to local people could improve decision making. This article examines the usefulness of explicitly asking what is important to local people. Our examples draw on biodiversity surveys in East Kalimantan (Indonesian Borneo). With local communities we characterized locally valued habitats, species, and sites, and their significance. This process clarified various priorities and threats, suggested refinements and limits to management options, and indicated issues requiring specific actions, further investigation, or both. It also shows how biological evaluations are more efficient with local guidance, and reveals potential for collaborations between local communities and those concerned with conservation. Such evaluations are a first step in facilitating the incorporation of local concerns into higher-level decision making. Conservationists who engage with local views can benefit from an expanded constituency, and from new opportunities for pursuing effective conservation.

There exists a negative externality of livestock breeding due to the difference between private and social breeding cost in Xilingol Biosphere Reserve (XBR), Inner Mongolia, that has caused extensive ecological degradation of the grassland. The property rights regime, the household production responsibility system (HPRS), was adopted in the 1980s to increase livestock production in XBR. Although HPRS has successfully increased production by promoting private economic interests, it has led to grassland degradation due to inefficient enforcement of stock rate. Through interviews conducted with government representatives and herding families in all management units of XBR, we elucidate the shortfalls of the current management regime and the Fencing Grassland and Moving Users policy initiated in 2002 to restore grassland. We propose an alternative property rights regime, small-scale co-management, to concurrently promote both individual economic interests and grassland conservation by improving the enforcement of stock rate.

To improve coral reef management, a deeper understanding of biodiversity across scales in the context of functional groups is required. The focus of this paper is on the role of diversity within functional groups in securing important ecosystem processes that contribute to the resilience of coral-dominated reef states. Two important components of species biodiversity that confer ecosystem resilience are analyzed: redundancy and the diversity of responses within functional groups to change. Three critical functional groups are used to illustrate the interaction between these two components and their role in coral reef resilience: zooxanthellae (symbiotic micro algae in reef-building corals), reef-building corals, and herbivores. The paper further examines the consequences of undermining functional redundancy and response diversity and addresses strategies to secure ecological processes that are critical for coral reef resilience.

The silica deficiency hypothesis holds that increases of still waters caused by hydraulic alterations and high nitrogen (N) and phosphorus (P) discharges enhance the growth of freshwater diatoms, which take up the dissolved silicate (DSi) supplied by natural weathering. The consequent decrease in the DSi supply to the sea is advantageous to flagellates (nonsiliceous and potentially harmful) but not to diatoms (siliceous and mostly benign) in coastal marine ecosystems. Verification of this hypothesis has been hampered by lack of relevant data, particularly in Asia. We investigated the aquatic continuum composed of Lake Biwa, the Yodo River, and the Seto Inland Sea, Japan, where the natural conditions make the silica deficiency less likely to emerge due to the inherently rich supply of DSi. The results showed that the silica was retained both in the lake and nearby the estuary. The relative dominance of diatom and flagellates could not be explained solely by the stoichiometric arguments but by the supportive discussion on the difference of their behavioral characteristics and the process nearby the estuary, where direct inputs of N and P and effluent Si enhanced diatom bloom, even though the Si/N ratio was lowered in the upstream reservoir. Thus the retention of DSi occurred in two places: in the lake and nearby the estuary, where the other N and P are loaded directly. The rate of DSi retention correlated with socio-economic changes, such as rapid economic growth in the 1960s and mitigations implemented after the 1980s. Sensitivity of this continuum to the Si processes suggests the global significance of this hypothesis.

Salix fragilis is the most common willow species grown extensively under the indigenous agroforestry system in the cold desert of Lahaul valley located in the northwestern Himalayas, India. Presently, this tree is under severe pest attack, and other infections have made its survival in the area questionable. This deciduous multipurpose tree species provides vegetation cover to the barren landscape of Lahaul and is a significant contributor of fuel and fodder to the region. This study is a detailed profile of the plant in three villages within this region: Khoksar, Jahlma, and Hinsa. The willow provided 69.5%, 29%, and 42% of the total fuelwood requirements of Jahlma, Khoksar, and Hinsa respectively. A striking observation was that only 30.0 ± 20.1% trees were healthy: 55.2 ± 16.1% of the willows have dried up and 14.8 ± 6.1% were in drying condition due to a combination of pest infestation and infection. To sustain this cultivation of willow under the existing agroforestry system in the region, we recommend that locally available wild species and other established varieties of willow growing in similar regions of the Himalayas be introduced on a trial basis.
